Fixed bugs in undo logging
Fixed bug where head block was split before min_row_length (caused Maria to believe row was crashed on read)
Reserved place for reference-transid on key pages (for packing of transids)
ALTER TABLE and INSERT ... SELECT now uses fast creation of index
Known bugs:
ma_test_recovery fails because of a bug in redo handling when log is cut directly after a redo (Guilhem knows how to fix)
ma_test_recovery.excepted is not totally correct, because of the above bug
mysqld sometimes fails to restart; Fails with error "end_of_redo_phase: Assertion `long_trid != 0' failed"; Guilhem to investigate
include/maria.h:
Prototype changes
Added current_filepos to st_maria_sort_info
mysql-test/r/maria.result:
Updated results that changes as alter table and insert ... select now uses fast creation of index
mysys/mf_iocache.c:
Reset variable to gurard against double invocation
storage/maria/ma_bitmap.c:
Added _ma_bitmap_reset_cache() (needed for repair)
storage/maria/ma_blockrec.c:
Simplify code
More initial allocations
Fixed bug where head block was split before min_row_length (caused Maria to believe row was crashed on read)
storage/maria/ma_blockrec.h:
Moved TRANSID_SIZE to maria_def.h
Added prototype for new functions
storage/maria/ma_check.c:
Simplicy code
Fixed repair_by_sort to work with BLOCK_RECORD
- When using BLOCK_RECORD or UNPACK create new Maria handle
- Use common initializer function
- Align code with maria_repair()
Made some changes to maria_repair_parallel() to use common initializer function
Removed ASK_MONTY section by fixing noted problem
storage/maria/ma_close.c:
Moved check for readonly to _ma_state_info_write()
storage/maria/ma_key_recover.c:
Use different log entries if key root changes or not.
This fixed some bugs when tree grows
storage/maria/ma_key_recover.h:
Added keynr to st_msg_to_write_hook_for_undo_key
storage/maria/ma_loghandler.c:
Added INIT_LOGREC_UNDO_KEY_INSERT_WITH_ROOT
storage/maria/ma_loghandler.h:
Added INIT_LOGREC_UNDO_KEY_INSERT_WITH_ROOT
storage/maria/ma_open.c:
Added TRANSID to all key pages (for future compressing of trans id's)
For compressed records, alloc a bit bigger buffer to avoid valgrind warnings
If table is opened readonly, don't update state
storage/maria/ma_packrec.c:
Allocate bigger array for bit unpacking to avoid valgrind errors
storage/maria/ma_recovery.c:
Added UNDO_KEY_INSERT_WITH_ROOT & UNDO_KEY_DELETE_WITH_ROOT
storage/maria/ma_sort.c:
More logging
storage/maria/ma_test_all.sh:
More tests
storage/maria/ma_test_recovery.expected:
Update results
Note that this is not complete becasue of a bug in recovery
storage/maria/ma_test_recovery:
Removed recreation of index (not needed when we have redo for index pages)
storage/maria/maria_chk.c:
When using flag --read-only, don't update status for files
When using --unpack, don't use REPAIR_BY_SORT if other repair option is given
Enable repair_by_sort for BLOCK records
Removed not needed newline at start of --describe
storage/maria/maria_def.h:
Support for TRANSID_SIZE to key pages
storage/maria/maria_read_log.c:
renamed --only-display to --display-only
